Smooth processes need the right coating

nonwoven materials industry

At production speeds of 1000 m/min., even light plastic and nonwoven materials can corrode surfaces. Aluminum surfaces and nonstick coatings quickly wear off in many applications. Wear from SAP powder, hot melt residue and material deposits, guides and angle bars with high friction, glue adhesions on vacuum drums or Lycra fibers that wear out the guides - these are just a few of the factors that require maintenance and lead to downtime.

Each component has unique requirements in the production process. Impreglon has developed coatings to increase your machines' service life, improve your processes and reduce costs. Impreglon offers an array of solutions with exceptional nonstick properties and unrivaled resistance to wear, with its customer-oriented coatings and selection of suitable filler materials - the answer to increasing quality and productivity.

Applications

At high speeds, the coating must be adapted perfectly to suit the application. We have three examples of how this can be achieved.

Sanitary pads (nonstick coating)

Sanitary pads/panty liners

In the production of sanitary pads, self-adhesive strips are attached to the bottom of the panty liners to prevent slipping and ensure maximum comfort.

Prevention of adhesion to vacuum rolls

Residue sticking to the vacuum rolls is a frequent occurrence when processing the sticky strips.

TempCoat®

The favorable nonstick properties of TempCoat®, combined with a smooth surface resistant to wear, ensure uninterrupted production.

Short cleaning time, improved processes

Reduces downtime and saves time spent cleaning.

Wear resistant slide coatings with nonstick properties

The TempCoat® coating procedure creates polymer and fluoropolymer layers with outstanding nonstick properties and very good sliding properties.

With additional reinforcement layers, slide coatings can be combined with high resistance to wear.

TempCoat® coatings can be applied on aluminum, steel, stainless steel, copper, ceramics and even plastics.

Temperature range: -40 °C to +285 °C
Surface roughnesses (Ra): up to approx. 1.0 µm
FDA approved: yes, with a few coating types

Nonwoven materials (nonstick coating & corrosion protection)

Non-woven materials

In the non-woven materials manufacturing process, cellulose is passed over drying drums, which in turn run over large rolls. The cellulose is dehydrated by the drying drums and converted into a web of fabric step-by-step.

High speed and high wear

The residual moisture causes the material to stick to the rolls. Combined with high production speeds, this means that the surfaces of the rolls are subjected to high levels of wear. The warm, humid environment promotes corrosion.

PlasmaCoat® and MagnaCoat®

A special combination of PlasmaCoat® and MagnaCoat® provides the necessary mechanical stability, excellent corrosion protection, outstanding nonstick properties and very good barrier protection in an aggressive hot and humid environment.

Optimal productivity, reduced downtime

Prevents machine downtime and expensive damage. Time-consuming cleaning measures can be eliminated and productivity is increased considerably.

Wear-resistant combination coatings

The PlasmaCoat® coating procedure combines the outstanding surface hardness and wear resistance of thermally sprayed metal or ceramic coatings with the nonstick and sliding properties of polymers and fluoropolymers.

PlasmaCoat® combination coatings also offer very good traction properties with various degrees of surface roughnes and profiles. An embedded metal or ceramic coating can be used as a substrate for the coating that protects from wear.

Coating thicknesses: 80 µm to 295 µm
Temperature range: -40 °C to +270 °C
Surface roughnesses (Ra): 1.5 µm to 17.5 µm
Surface hardness: 28 to 70 HRc
FDA approved: yes, with certain coating types

Polymer coating systems for heavy-duty corrosion protection

MagnaCoat® coatings are thick-film polymer and fluoropolymer coatings with a virtually non-porous surface. They offer excellent corrosion resistance, good nonstick properties and high electrical impact resistance, even at high temperatures. The coatings also provide excellent barrier protection to resist aggressive chemicals.

MagnaCoat® polymer coatings can be applied to all surfaces made of aluminum, steel, stainless steel or other alloys.

Coating thicknesses: 100 µm to 800 µm
Temperature range: -40 °C to +260 °C
Surface roughnesses (Ra): up to approx. 1.5 µm

Nonwoven material (nonstick coating)

Non-woven material

In the production of non-woven materials, wet strips are dried with streams of hot air applying the suspension drying principle. In the process, the strip is transported without contact by a series of air cushions at speeds of approx. 305 m/min.

Prevention of blockage in the dryer nozzles

It is imperative for the production environment to be absolutely clean in order to ensure high quality. When the production line is started and stopped, the web tension can vary and material that has not yet dried can stick to the surface of the nozzles.

PlasmaCoat®

The PlasmaCoat® coating prevents the strip material from adhering and reduces the accumulation of suspended matter from the environment. It can prevent partial or total blockage of the dryer nozzles.

Reduced downtime, improved productivity

Prevents machine downtime and time-consuming cleaning and maintenance work. Significantly increases productivity.
